1) At the Merapi volcano, Indonesia, a large scale pyroclastic flow occurs after several small scale failures of the lava dome, as is the case of the Unzen volcano, Japan. This fact confirms the necessity of the joint research.2) Preparation of GPS survey has been done in Bandung area.3) Field investigation and the data analysis of the condition of occurrence of debris flow in the volcanic area and the sediment runoff and river evolution in the Brantas river system have been done.4) At the Sanur beach, Bali Island a system has been set to observe several maritime phenomena all year round and an observation of the littoral current on the coral reef has been performed.5) Field investigation of the situation of the disaster and the nonstructural measures for the disaster has been done.6) For the purpose of establishing a seismotectonic model covering the Japanese island arc and the continental China, the seismicity data from these regions for the past 100 years have been compiled and analyzed from the view point of the physical mechanism of seismic activities and tectonics of this region.7) Strong motion observation instrumentation for the purpose of microzonation was completed in Tangshang, China. Observation activity has started.8) For the purpose of urban seismic risk assessment of the Shanghai area, China, arrangements have been made for long-period microtremor observation and analysis for vulnerability assessment of buildings in the region.9) Site measurements have started on landslides at the Fua Ching Chi, China. Soil samples were obtained, and laboratory tests have been performed.10) Mechanism of glacier surge debris flow in eastern Tibet of China has been studied, and their instrumental observation plan has been established.

1)在印度尼西亚的默拉皮火山，大规模的火山碎屑流发生在熔岩圆顶的几个小规模的故障，是日本的云仙火山的情况。2）在万隆地区进行了GPS测量的准备工作; 3）对火山区泥石流发生条件和Brantas水系的泥沙径流和河流演变进行了实地调查和资料分析; 4）在沙努尔海滩，巴厘岛建立了一个全年观测若干海洋现象的系统，并对珊瑚礁上的沿岸的海流进行了观测。6）为了建立覆盖日本岛弧和中国大陆的地震构造模型，从地震活动的物理机制和区域构造的角度，对这些地区近百年来的地震活动资料进行了整理和分析。7）中国唐山完成了用于小区划的强震观测仪器。8）为了对中国上海地区进行城市地震危险性评估，已经安排进行长期的微震动观测和分析，以便对该地区的建筑物进行脆弱性评估。10）研究了西藏东部冰川涌浪泥石流的形成机制，制定了仪器观测方案。
